Abstract
The present disclosure provides display substrate and display device, and belongs to the field of display technology. The display substrate of the disclosure has mounting region, first display region adjacent to mounting region, and second display region surrounding first display region and/or mounting region. The display substrate comprises: substrate; driving circuit layer on substrate and comprising pixel driving circuits in first display region and second display region, and arrangement density of pixel driving circuits in second display region is less than that of pixel driving circuits in second display region; and light emitting devices in mounting region, first display region, and second display region, first electrode of each light emitting device being electrically coupled to a corresponding pixel driving circuit, and pixel driving circuit electrically coupled to first electrode of light emitting device in the mounting region being located in first display region.
